Weather Satellite - Research Article from World of Earth Science

The first attempt to look at Earth's weather from space occurred early in the space program of the United States. In 1959, Vanguard II was launched with light-sensitive cells able to provide information about Earth's cloud cover. Unfortunately, the satellite tumbled in orbit and was unable to return any information. Explorer VI, also launched in 1959, was more successful and transmitted the first photographs of Earth's atmosphere from space.

In 1960, the United States launched the first experimental weather satellite, TIROS 1. The acronym for Television and Infra Red Observation Satellite, TIROS 1 televised over 22,000 photos before it failed six weeks later. It detected potential hurricanes days before they could have been spotted by any other means. It watched the spring breakup of the ice in the St. Lawrence River and helped forecast weather for the Antarctic bases. TIROS 1 also used infrared detectors to measure the amount of heat radiated by...
